Testtömegcsökkenés

Testtömegcsökkenés, commonly referred to as weight loss, is the reduction of total body mass. This can occur through a number of means, including loss of fluid, body fat, or muscle. It can also be a consequence of disease or the aging process. Intentional weight loss is often pursued for health or aesthetic reasons. Unintentional weight loss can be a sign of an underlying medical condition and warrants medical attention.

The primary mechanism for intentional weight loss is achieving a caloric deficit, meaning that the body expends more calories than it consumes. This can be accomplished through a combination of dietary changes and increased physical activity. Dietary modifications typically involve reducing the intake of calorie-dense foods, such as those high in fats and sugars, and increasing the consumption of nutrient-rich, lower-calorie options like fruits, vegetables, and lean proteins. Regular exercise burns calories and also contributes to overall health by improving cardiovascular function, building muscle mass, and boosting metabolism.

Unintentional weight loss, where a person loses weight without trying, can be caused by various factors. These can include medical conditions such as hyperthyroidism, diabetes, certain cancers, digestive disorders like celiac disease or Crohn's disease, and infections. Psychological factors like stress, anxiety, and depression can also lead to a loss of appetite and subsequent weight loss. If significant unintended weight loss occurs, it is crucial to consult a healthcare professional to diagnose and treat the underlying cause.
